Abstract
ABSTRACT OF THE DISCLOSURE:
A vehicle hoist having four separate pivoting shafts.
Each shaft is pivotally and slidingly mounted at its lower end on a transversal cylindrical beam which is fixed on a frame. The shaft is adapted to move between a horizontal and a vertical position. The fra-me is fixed on a base structure and adapted to longitudinally slide on it. The top of each shaft is pivotally connected to an anchoring member which is adapted to grip the rocker panel pinchwelds of the ve-hicle. When the vehicle is pulled horizontally, the four shafts grip-ping the vehicle, raise the latter. Abutting component stop and hold the shafts in their upright position. The transversal and longitudin-al movements are provided to adjust to the width and the length of the different types of vehicles.

Prior art:
Numerous patents related to the vehicle repair art dis-close devices comprising one or more hydraulically operated posts which are provided on their upper ends with arms which move through horizontal planes to engage with the frame o~ the vehicLe to be rais-ed.
~owever, this type of hoisting device is considered qui-te expensive in regards to its installation cost and relatively unef-ficient because of the limited access to the underside oE the vehicle and the restrictive number of tasks they can performed. Indeed, opera-tions like the straightening of a vehicle frame cannot always be ade-20~ quately performed on such known type o~ hoisting device.
Since there exists a large number of so called "body : : :
shops" specializing in the repair of collision damaged vehiclesJ the-re is a need for quickly raising an holst Ing device which can be used for a variety Oe tasks including the straightening of frames.
Patent such as U.S. patents nos 1,942,945 and 4,447,042 discloses vehicle lifts using X-shaped structures with pistons for hoistin~ cars. The U.S. patent no 4,277,049 is directed to a lift structure for servicing vehicles. All four elevating members are syn-chronized by a pair of supporting members.

Known hoisting devices, only partially fullfill some of the above mentioned needs. These dev;ces are generally not easy to ma-nipulate, are mechanically complicated and therefore relatively ex-pensive.
SU~MA~Y ()F T15~ INVF.NTION
The invention relates to a substantially simplified structure particularly adapted for use in connection with the strai~htening of collision damaged vehicles.
The vehicle hoisting mechanism requires no hydraulic or pneumatic piston components to litt the vehicle, therefore rendering the system safer to the operator.
The vehicle hoisting device according to the invention which is fast and easy to operate since it is provided with efficient fastening means.
It is Eurther an object of the invention to provide a vellicle hoisting device which does not require much storing space and whlch can be adapted ~o conventional car platforms.
The vehicle hoiating device according to the invention is readily adapted to vehicles of different widths and lenghts.
The hoisting structure comprises a set of pivoting shafts allowing the vehicle body to be lifted upon horizontal trac-tion on the body by a simple pulling device such as a small winch.
The shafL is pivotally mounted at bo~h ends to move between A substan-tially hori~ontal and a substantially vertical position.

A hand clamp 22 (fig.6) or o~her sui~able means ;s pro-vided to hold the component 2~ and to maintain shaft 18 in the verti-cal position. Anchoring means snch as conventionally known anchor clamps 24 are pivotally mounted at the other end of shaft 18 and are used to grip the rocker panel pinchwelds 26 of the vehicle 28 and hold the shafL 18 in its upright position. Tightening means such as nut and bolt arrangement 30 is used to secure a plate 29 connecting - the anchor clamps 24 in a fixecl position relative to shaft 18. ~ach of the pivoting structure 12 is adapted to be clamped to the vehicle body when it is upwardly tilted manually as shown in iigure 3. ~hen the body of the vehicle 28 is pulled along an horizontal direction, such as by the chain 31, the shaft l8 freely pivots around beam 16 to a vertical portion and anchor clamps 24 pull the vehicle in its rais-ed position. When seen from the side of the vel~icle or as illustrated in figure 1, the combination formed by the undercarriage or rocker - ~ panel 26 of the vehicle 28, the ground 32 and two pivoting structures 12 represents a parralelogram which is modi~ied as the vehicle is being pulled ~ith the undercarriage of the vehicle 28 remaining par-ralel to the ground 3Z at all times.

In ~he preEerred embodiinent, the plate 29 connecting the anchor clamps 24 is pivotally mount:ed on sha~ IX by means of a sleeva system comprising an inner cylindrical sleeve 34 rotatably in-serted in an outer cylindrical sleeve 36. A larger groove 38 is pro-vided in the outer .sleeve 36 to allow sliding of a washer type ele-ment 40 while a narrow gro(Jv~ 42 in the inner sleeve 34 is provided to allo~" pivoCing of fastening bolt 44. When the inner sleeve 34 is properly positioned relatively to the outer sleeve 36, bolt 44 ex-tends through both sleeves 34 and 36 and ;s tightened with a nut 4i~

Panels 50 are rigidly linked by welding or by other suitable manner to a fixation plate 52. The top fixation pla-te 52 rests on the inner flanges 54 of two lateral "I-beams" 55 form-ing the structure of pathway 56.
A bottom fixation pLate 58 is used in conjonction with f~stening means such as bolts 60 to clamp flanges 54 and to longitud;-naLly f;x frame 14 in the pathway 56. When noL in use, pivoting struc-ture 12 can be concealed ins ide a recess 62 located between the two "1-beams" 55 and below a cover plates 63.
